SFR surface density (∑_SFR) obtained from the Hi-GAL clumps (left) and modeling of the high-mass stellar population (right) in a 6 kpc × 6 kpc area centered on the Sun (indicated with the yellow star). The labels give the positions of the sources in the “Handbook of Star-Forming Regions” (Reipurth 2008a,b) with the distances estimated in Zucker et al. (2020). The dashed lines correspond to galactocentric circles with the indicated radii.
